Enable Protocol Logging for POP3 and IMAP4

You can configure protocol logging settings for POP3 and IMAP4 on an Microsoft Exchange Server 2010 Client Access server. Protocol logging isn't enabled by default. You can use protocol logging to review the POP3 and IMAP4 connections in your Exchange environment. This can be useful if you're troubleshooting issues related to POP3 or IMAP4 performance.

Protocol logging can be enabled or disabled using the Shell. Optionally, you can enable, disable, and modify protocol logging options by editing the Microsoft.Exchange.Pop3.exe.config and Microsoft.Exchange.Imap4.exe.config configuration files located on your Microsoft Exchange Server 2010 Client Access server.

If you want to change the default protocol logging settings, review the following table, which contains parameters that define how protocol logging works for POP3 and IMAP4. Then, modify the settings in the Microsoft.Exchange.Pop3.exe.config or Microsoft.Exchange.Imap4.exe.config configuration file.

Parameters you can configure for protocol logging

Parameter name

Description

AgeQuotaInHours

This value defines how often the protocol log file will be re-created. By default, the value is set to 24.

SizeQuota

This value defines the size limit after which the protocol log will automatically be re-created. By default, the value is set to 10000000. However, if the file size doesn't exceed this value, the file will be re-created automatically at the time interval based on the value specified by the AgeQuotaInHours parameter.

PerFileSizeQuota

This value defines the byte file size above which a new file will be created. By default, this is set to 1000000. The protocol log file will create a new protocol log file every time that this value is exceeded.

Save, and then close the Microsoft.Exchange.Pop3.exe.config file or the Microsoft.Exchange.Imap4.exe.config file.
